DC POWER TIMING LIGHT
The DC power timing light, in modern pistol grip styling, is a compact,
durable test instrument. The light is equipped with a special high-intensity
xenon lamp which allows timing of engines even in bright surroundings.
designed to operate between 11 volts and 16 volts and is equipped with special
protective circuitry to prevent damage if subjected to higher voltages. The
light is provided with a spring loaded trigger and long fuel and oil resistant
hookup leads. The transistorized circuitry incorporates the latest electronics
advances and assures a long, trouble free life.
Engine timing is the term applied to the relationship of piston travel and
moment of spark in a gasoline engine. Timing requirments vary from engine to
engine, and before attempting timing adjustments, the engine manufacturer's
specifications must be obtained. It should be noted, however, that due to the
many variables involved, such as temperature, humidity, elevation, fuel octane
rating, and engine conditions published timing data must be considered as
approximate and some tolerance is permissible.
